SAILING VE'SSEL Filed June 13, 1963 2 Sheets-Sheet 1 INVENTOR P 1965 H. G. THORNDIKE 3,205,849 I SAILING VESSEL Filed June 15, 1965 2 Sheets-Sheet 2 United States Patent 3,205,849 SAILING VESSEL Henry G. Thorndike, Wicomico Church, Va. Filed June 13, 1963, Ser. No. 287,537 20 Claims. (Cl. 114102) This invention relates to wind driven vehicles and more particularly to a novel sailing vessel. This invention further contemplates a novel rigging assembly for fore and aft rigged sailing vessels.

In the art of sailing, it has been found that the forward component of driving force along the centerline of a sailing vessel, resulting from the incident of wind on the sails, is partly provided by the direct impingement of air on the windward side of the sails and partly, although to a greater extent, by the suction effect produced by the flow of air on the leeward side of the sails. This suction effect is produced as a result of the fact that air on the leeward side of the sail travels a greater distance around the sail to reach the leech, in the same time as air traveling along the shorter windward side of the sail. Consequently, the leeward flow of air must travel at a greater velocity than the windward flow, whereby the difference in velocities produces a decreased pressure on the leeward side of the sail. The pressure differential across the sail resulting from the velocity differential produces a force on the sail directed perpendicular to the surface thereof.

In conventional fore and aft rigs having a mainsail and club jib, optimum advantage of this phenomenon is obtained when the sails are trim-med in and the vessel sailed close-hauled with the apparent wind approximately 30 off the forward projection of the vessel because only under such conditions will the lateral dimensions of the vessels hull provide terminal points for the vertical stresses necessary to maintain the sails in uniform curvature and aspect to the wind throughout their height.

In view of this phenomenon, it further has been found that the forward component of force of the mainsail can be increased by the use of a headsail, such as a .g-enoa jib, partially overlapping the mainsail and trim-med relative thereto to provide a slot therebetween having an enlarged opening between the mast and the headsail luff and a restricted opening between the mainsail and the headsail leech, substantially defining a nozzle. With the sails thus trimmed, air entering the slot is accelerated therethrough, decreasing the pressure on the leeward side of the mainsail, thereby increasing the pressure differential across the sail and, correspondingly increasing the forward component of driving force.

In conventional fore and aft-rigged sailing vessels, such ideal sailing conditions can be obtained only when the vessel is on a heading approximately 30 off the apparent wind and the sails are trimmed to produce the slot effect. When the heading or the relationship of the sails is changed as would reasonably be required, the advantages of the aforementioned interrelationship of the sails and the presentation thereof to the wind is lost.

Accordingly, it is the principal object of this invention to provide a novel fore and aft rigged sailing vessel having a maximum forward component of driving force regardless of heading.

Another object of this invention is to provide a novel fore and aft rigged sailing vessel whereby the sails may be set in their most efficient relationship to produce a maximum forward component of driving force.

A further object of this invention is to provide a novel fore and aft rigged sailing vessel wherein the sails may be presented to the wind at their most efiicient angle to produce a maximum forward component of driving force.

Cir

3,205,849 Patented Sept. 14, 1965 A still further object of this invention is to provide a fore and aft rigged sailing vessel wherein the saids may be set in their most efficient relationship on either tack, and presented to the wind at their most efficient angle, regardless of the vessels heading, to produce a maximum amount of forward component of driving force.

Another object of this invention is to provide a novel fore and aft rigged sailing vessel wherein the sails may be set in their most efficient relationship and presented to the wind at their most efficient angle, which provides for adjustment to compensate for variations in the strength of the wind, the nature of the sea and the characteristics of the sailing vessel.

A further object of this invention is to provide a novel fore and aft sailing vessel wherein the sails can be presented to the wind on most headings wherein the angle of wind incident on the sails is uniform from head to foot.

A still further object of the present invention is to provide a fore and aft rigged sailing vessel wherein the stresses developed in the rigging are balanced rather than transmitted to the hull of the vessel as in conventional vessels.

Another object of the present invention is to provide a novel rigging assembly for fore and aft rigged sailing vessels.

Other objects and advantages of the present invention will become apparent to those skilled in the art, from the following description when read in conjunction with the accompanying drawings, wherein:

FIGURE 1 is a side elevational view of an embodiment of the invention,ha'ving a portion thereof broken away;

FIGURE 2 is across-sectional view taken along line 22 in FIGURE 1;

FIGURE 3 is an enlarged cross-sectional view taken along line 33 in FIGURE 2, having portions thereof broken away;

FIGURES 4-9 are diagrammatic top plan views of the embodiment shown in FIGURE 1, illustrating the inven-. tion with alternate rigging arrangements, headed on Various courses relative to the direction of the apparent wind on either the port or starboard tack; and,

FIGURE 10 is an enlarged fragmentary view of the embodiment shown in FIGURE 2, illustrating the hinge connection of one of the outriggers to the main body of the rigging assembly.

In accordance with the broad aspects of this invention, there is provided a fore and aft rigged, wind driven vessel having means disposed parallel to the deck of the vessel to which the contact points of the sails may be secured for arranging the sails in their most efiicient relationship and which is rotatably mounted on a mast of the vessel so that it may be rotated as an integral unit independent of the hull of the vessel, whereby the sails prearranged in their most efiicient relationship may be presented to the wind at their most eflicient angle regardless of the direction of the apparent wind, without changing course.

Referring to the drawings, there is shown a preferred embodiment of the present invention. Numeral 20 designates the hull of a sailing vessel, having a mast 21 mounted forward on the centerline thereof. Spaced parallel from the deck of the hull and rotatably mounted on the mast is a rigging assembly 22 comprising a pair of side members 23 and 24 joined at the forward ends thereof defining a V-shaped frame. Interconnecting the side members, substantially intermediate the ends thereof, is a cross member 25 disposed perpendicular to the centerline and in the plane of the frame. The cross member 25 is provided with a fitting 26 disposed on the centerline of the frame for pivotally connecting the frame to a gooseneck fitting 27 mounted on the mast 21. Pivotally mounted on the aft side of the cross member on the centerline of the frame is a boom 28 which is adapted for pivotal movement in the plane of the frame between the side members 23 and 24. The boom 28 extends rearward of the ends of the frame and is partially supported by means of a traveller or support member 29 interconnecting the aft ends of the side members 23 and 24 and disposed below the plane of the frame. The underside of the boom has a rigid strap 30 straddling the support member 29 to prevent displacement of the boom relative to the plane of the frame.

The sailing vessel is rigged with a mainsail 31 which is secured along its foot 32 to the boom 28 and along its luff 33 to the mast 21. The mainsail is hoisted on the mast and suitable tension is provided along the luff by means of -a conventional mainsail halyard as is well known in the art. The headsail may consist of, alternately, either a club jib 34 shown in dot-dash lines in FIGURE 1, or an overlapping or genoa jib 35 shown in solid lines. The tack 36 of either the club or genoa jib is secured to a lower terminal for the jib stay 37 to which the luff 38 of either jib is secured. The jib is hoisted on the mast and suitable tension is provided along the luff by means of a jib halyard as is conventional practice in the art.

When the club jib 34 is used, it is sheeted to a thwartship traveler 39 mounted on the frame forward of the mast, disposed perpendicular to the centerline of the frame. As best shown in FIGURES 2 and 3, the jib sheet 40 is provided with a slide member 41 mounted on the traveler 39 for transverse sliding movement thereon. As soon as the club jib is bent and hoisted on the jib stay, the jib is trimmed as desired and the length of the jib sheet 40 is adjusted correspondingly. Once the jib sheet 40 has been initially adjusted, no further adjustment is necessary and the club jib is free to swing from side to side similar to the mainsail boom when changing tack. It also will be appreciated that transversely spaced limit stops are provided on the traveler 39 for the slide member 41.

When the genoa jib 35 is used, it is bent and hoisted in the same manner as the club jib except that the jib is sheeted selectively to a port outrigger 42 or a starboard outrigger 43 mounted on the rearward ends of side members 23 and 24, respectively. The outriggers 42 and 43 are hingedly mounted on the side members, as best illustrated in FIGURE 10, so that they can be swung downwardly to serve as a crutch for the frame, or swung outwardly and locked in the outboard position as shown in FIGURE 2 to provide terminals for the jib sheet 44 of the genoa jib. The outriggers are provided with a latch 43a for locking them in the outboard position. It will be appreciated that, contrary to the sheeting arrangement for the club jib, the genoa jib must be released from one outrigger and sheeted to the other when changing tack in a manner similar to conventional rigs.

The rigging assembly may be constructed from any suitable material, although a light weight metal having high strength properties such as aluminum is preferred. The dimensions of the component parts of the rigging assembly and their interrelationships, including the length and included angle of the side members, the lateral spacing of the limit stops of the mainsail boom, the position and lateral spacing of the limit stops of the traveler mounted forward of the mast, and the positions of the sheeting terminals of the outriggers, will differ according to the size and other characteristics of the vessel on which the assembly is mounted. The rigging assembly is sheeted to the hull by a sheet or tackle 45 which may be secured at the forward end of the frame, at the after end of the frame or at any point on the mainsail boom between its aft-er extremity and the point of its engagement with the support member 29.

In setting up the rig, the mainsail is first hoisted in a manner similar to that of conventional fore and aft rigs. When a club jib is to be used, it then is hoisted on the jib stay in a manner similar to conventional fore and aft rigs, sheeted to the thwartship traveler 39 and trimmed to provide a desired draft in the jib. Once the club jib has been set, no further adjustment is required. When a genoa jib is used, in lieu of a club jib, it is hoisted on the jib stay and tension is established along the luff 38. The tensions provided on the luff of the genoa jib and the leech of the mainsail establish a stable system of forces in a vertical plane about a fulcrum located at the pivotal connection of the rigging assembly to the mast. The entire sail plan then becomes a rigid pattern in this plane, without imposing any stresses on the hull of the vessel. The genoa jib is sheeted selectively to either of the Outriggers and trimmed to establish the aforementioned slot between the genoa jib and the mainsail.

The tensile stress at the point of engagement of the boom 28 with the traveller 29 actually is distributed by the boom along the entire foot of the mainsail, serving to hold the mainsail spread to the full extent of its area at all times. It will be appreciated that when the rig is set up, the pressure of the wind against the mainsail results in an upward force exerted on the aft end of the assembly, which acting about the pivotal connection of the frame with the mast as a fulcrum, causes a downward force on the forward end of the assembly, holding the jib lufl taut and straight. The pressure of wind against the jib similarly results in an upward force exerted at the forward end of the assembly, which acting about the pivotal connection of the frame to the mast as a fulcrum, causes a downward force at the aft end of the assembly, holding down the mainsail boom. These counteracting forces acting on the jib and mainsail have a tendency to balance each other while maintaining the luff of the jib and the entire area of the mainsail taut and straight. Furthermore, it will be appreciated that these forces in conventional rigs normally would be transmitted to the hull, where undesired stresses would be developed.

After the sails have been set relative to each other on the rigging assembly, the assembly can be rotated in a plane parallel to the deck of the hull and presented to the wind at its most eflicient angle of incidence, as illustrated in FIGURES 4 through 9. Referring to FIGURE 4, there is shown a top plan view of the invention rigged with a mainsail and club jib heading on a course approximately 30 off the direction of the apparent wind on the port tack. The rigging assembly here is aligned with the centerline of the hull. The mainsail is shown deflected to leeward at an angle selected to suit prevailing conditions and determined by adjustable stops mounted on the traveller 29. The club jib also is deflected to leeward at an angle determined by the stops on the thwartship traveller, and having the sheet thereof adjusted to suit the draft of the jib and to obtain maximum drive from the club jib without back winding the mainsail.

FIGURE 5 is similar to FIGURE 4, with the sails deflected on the opposite side of the frame for sailing on the starboard tack.

FIGURE 6 is a top plan view of the invention similar to FIGURE 4, but with a genoa jib set in place of the club jib. The mainsail is shown deflected to leeward at an angle determined as described above. The genoa jib is shown sheeted on the leeward outrigger and adjusted to provide the desired slot between the jib and mainsail.

FIGURE 7 is similar to FIGURE 6, showing the sails deflected on the opposite side of the rigging assembly for sailing on a starboard tack.

FIGURES 8 and 9 illustrate the invention rigged similar to that shown in FIGURES 6 and 7, and further illustrate the orientation of the rigging assembly relative to the centerline of the vessel, with the apparent wind abeam, and with the apparent wind over the quarter, respectively.

It thus will be appreciated that there is provided a fore and aft rigged sailing vessel having means disposed parallel to the deck of the vessel to which the contact points of the sails may be secured for arranging the sails in their most eflicient relationship, and which can be rotated so that the sails can be presented to the wind at their most eflicient angle, regardless of the direction of the apparent wind.

From the foregoing detailed description it will be evident that there are a number of changes, adaptations and modifications of the present invention which come within the province of those skilled in the art.
